How do I get the characters after the last period in a string?

This seems so simple, yet I couldn't figure out the answer even after going through the list and strings functions in the docs for CF 8. I want to return the characters in the name of a photo preceding the period. i.e.. If the photo is named dog.jpg, I want to strip out .jpg from the filename so

Re: How do I get the characters after the last period in a string?

Use the list functions, with the period as the delimiter could there be more than one period? If so, you need to decide between two options (if not, then either will work) If you only want to remove the very last extension after the last period, cfset name=listDeleteAt(file,listLast(file,.),.)

RE: How do I get the characters after the last period in a string?

Jerry... You hit upon something I thought about after I posted my solution. Yes, there definitely could be more than one period, since these are user-uploaded images. I'll modify my code to use: #listdeleteat(file,listlast(file.'.'),'.') Now, I'm assuming that the code above will work if

Re: How do I get the characters after the last period in a string?

Because CFImage isn't supposed to be used as a file system manipulation? Even functions like fileMove() doesn't even have one. Only one that I'm aware that has a nameconflict attribute is CFFile action=upload. There's a reason why we have functions like fileExists(). On Nov 7, 2007 1:14 PM,

RE: How do I get the characters after the last period in a string?

You know... a better solution than what I've got, which is to only deal with as many as two periods in a filename, is needed. The current solution leaves some gaps if a user decides to user several periods as delimiters. And stripping out the periods, except for the one before the extension might

Re: How do I get the characters after the last period in a string?

this will work for 1 or more, but will NOT work for none! (it will return an empty string) you should do a listLen(file,.) gt 0 test to make sure before you start. On Nov 7, 2007 1:21 PM, Rick Faircloth [EMAIL PROTECTED] wrote: Jerry... I'll modify my code to use:

Re: How do I get the characters after the last period in a string?

^ = start of string \w = Word * probably isn't needed. This regex doesn't account for multiple . characters, but that's not to say that you can't make it. \w will probably need changed to something else. I'm a hack at this, not an expert. :) Trying to get there. Regex cheat sheet:

RE: How do I get the characters after the last period in a string?

Listlast(filename, '.') to get the extenstion And... ListDeleteAt(filename, listlen(filename, '.'), '.') to get everything except the extension (including the dot) It doesn't matter with either method whether there is 1 dot or 40. They will work as long as there is at least 1 dot present.
